Nintendo has announced that its Wii U gaming console will not feature a Blu-ray drive, and will instead stick to a proprietary disc format. Patent fees related to the technology are too high, the company explained. The Wii U will, however, compete with existing consoles in terms of hardware - it is equipped with a customized CPU from IBM and a GPU from AMD, and is rumored to be 50 percent faster than PS3 and Xbox 360.
